Date: Sun, 18 Nov 2012 18:47:02 +0800 From: Mark Ellis <m@...llis.com> To: linux-kernel@...r.kernel.org Subject: PROBLEM: REGRESSION in drivers/platform/x86/dell-laptop.c 1. rfkill code removal causes hang 2. the rfkill code was removed from this driver in commit 53039f222c548bfc119eea6df4dca2b57550e271 this results in my computer hanging (dell n5050) if booting with the wireless (hardware) disabled. downgrading this module to the version prior to this commit fixes the issue. 3. modules, laptop, dell-laptop, rfkill 4.
